It is easy to overlook, which is perhaps fitting for a structure whose date remains entirely unknown. The house site measures roughly five metres by four metres, its perimeter marked by an earthen bank about a metre and a half wide at the base and only a quarter of a metre high. On the south side, at the south-west corner, a gap of around three metres may represent where a doorway once stood.

Ringforts, roughly circular enclosures defined by earthen banks or stone walls, were the typical settlement form of early medieval Ireland, used as farmsteads and places of habitation from roughly the fifth to the twelfth centuries, though some were built and used across a far wider span of time. The house site here sits within the southern quadrant of such an enclosure, with two further low rises or platforms visible elsewhere in the interior, one to the north of the house site and another in the north-west quadrant. What these platforms represent is not recorded. Ushnagh Hill itself carries considerable symbolic weight in Irish tradition, long regarded as the mythological centre of Ireland, which lends an added layer of curiosity to what might otherwise seem an unremarkable scrap of earthwork. Whether the person or people who once occupied this modest rectangular space had any sense of that significance is, of course, impossible to say.
